WILLIAM o. 'MccILL, OF CINCINNATI, OHIO.

IMPROVED WINDLASS.

Specification forming part hf Letters Patent No. 46,811, dated March 14, 1865.

To all whom it may concern:

Be it known that I, WALLIAM O. MoGILL, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Windlass'es and I do hereby declare the following to he a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specifloat-ion.

My invention relates to devices for the prevention of fouling and slipping of- Windlasscables.

Figure 1 is a rear elevation of a Windlass embodying my improvement. Fig. isfa,

. transverse section of the same. A represents the drum or barrel of an ordiuary Windlass, journaled in suitable housings; B. The drum A is grooved cirevmferentially at a, to retain in position the first coil of the chain or cable or hawsers G, which is to he wound aroundthe barrel a sufi'icient number of turns to secure the requisite friction.

lrepresents that end of the cable from which the anchor or other object is suspended, and whose weight tends to draw the cable tightly around the barrel.

In the act of weighing anchor or hoisting any other heavy weight the cable on the ordinary Windlass is well known to be extremely liable to foul,-t-hat is to say, one coil of the cable is liable to lap or ride over another so as to interrupt the action of the Windlass.

It is to cure this defect that the leadingfeature of my improvement has been devised.

This feature consists 'in the provision of a plate, D,-called by me the divider. The plate D is firmly attached to the deck or other stationary object, from which it extendy obliquely upward, as shown. The plate D has a concave edge, d, formed to enter and snugly fit the groove a without quite touching the drum. The plate D acts to ease the second coil away from the first and to prevent fouling. The groove a acts in eo-opcration with the divider D to hold the first coil to its place and to keep the first and secondeoils separate.

The groove a constitutes the second material feature of my invention.

The thirdpart of my invention consists in the provision of a check-pawl, E, which is so hinged to the divider D as for its point to engage in the links'of one or more of the secondary set of, coils, and to catch or hold fast the cable automatically at any point desired;

. 3. The combination of the divider D d and D check-pawl E, substantially as set forth.

In testimony of which invention I hereunto set my hand.
